. Specification of LetitQrsP-atent.

Patented Dec. 1'7, 191.8.

Application filed May 14, 1918. Serial No. 234,542.

To all whom it may concern:

Be it known that I, EDWIN BALL STIMP- son, a citizen of the UnitedStates,-residing Brooklyn, county of'Kings, andstate of New York, haveinvented certain-new a r d useful improvements in Cartridge-Belts, ofwhich thefollowing is a specification.

My invention relates to-cartridgefeed1ng belts of the type used in rapidfire machine guns, and has for its object to provide an improved beltformed of .unsubstantial sheet material having reinforcing tensilemembers embedded therein.

In an application-for,;patent,-Ser. No.

filed byme on *May19, 1'9118,a cartridge belt of this general typewasshown and described which consisted of two strips of light andunsubstantial sheet material, such s paper, reinforced alongfthe centerand at either edge with a cord or thread'designed to increase thetensile strength of thebelt as a whole. The two strips making up thebeltwere preferably attached to-each other by stitching togetherspacedaportions of the threaded portions at suitable inten vals to formcartrid e holding loops. "This form it of cartridge be t is highlysatisfactory and serviceable, but as I have continued-my experiments, Thave developed another arrangement ofgthe reinforcing threads and soutilized the new arrangementi that an improved manner for forming thecartridge holding loops has resulted and consequently a generallyimproved form of :belt of this a general nature has been obtained.

The principal feature of the inventionresides in the formation of a beltby meansof two superposed strips of material such as paper, each striphaving a plurality of reinforcing cords spaced apart andembedded thereinalong each lateral edge thereof, together with means for attaching thestrips to each other at points between the adjacent reinforcing cords,to form suitable cartridge holding loops.

Other features of the invention will be hereinafter described.

In the drawings,

Figure 1 is a view of a section of cartridge belt 3 embodying apreferred form of the invention and showing a number of cartridges inplace therein. 1

Fig. 2 is a view similar to Fig. 1 and showmg a modified form of meansfor at taching the belt strips together.

Fig. 3 is a view of a section of belt show mg the use of metallic clipsfor clamping the strips together to form the .belt.

Fig. l-,is a view showing the use of an ordinary form of staple withwhich the strips are attached together. 7

Fig. 5 is an enlarged sectional view showing'the folded paper stripsused to make up ,tlie belt.

' The cartridge feeding belt shown in the drawing comprises the strips 1and 2 formed of double strips of material such as paper or the'like,having two sets of reinforcing cords '3 and 4 embedded therein in twoslightly spaced apart positions along each lateral margin of the strips.The reinforcing .cords'3-and 4: are preferably of such a nature as tooffer a very substantial resistancegto breaking, so that they add in animportant degree to the tensile strength of the belt as a Whole.

The belt forming strips are preferably attached 'toeach f other atsuitably separated points .to' form cartridge holding loops by means ofmetallic fastening members taking various'forms. llhave found eyelets 5,such as are shown in Fig. 1,,to be well suited to the purpose inyicw,and by placing them in oppositelydisposed positions between the parallelreinforcing cords 8 and 4, near each lateral edge, any tendency that thematerial might otherwise have to tear as it is'bent over "the e'dge,ofthe eyelet is eliminated, since the tensionon the strip orweb is takenup byi'the reinforcing cords. This makes a very effective constructionand the eyelets can be rapidly fastened inrplace in making up the belts.It will be seen that the eyelet members 5 are wider near one margin ofthebelt than the other so as to form holding loops of different size tofit the correspondingly different diameters 6 and 7 of the car fridges.

It will be seen that by placing the reinforcing cords in groups, andpreferably in pairs, and making use of fastening members that exerttheir clamping effect on substantially theen'tire width of the materialbetween'the cordsin each pair,the cords are held in immovable relationwith respect to eachother and one cord cannot be pulled to a moreadvanced point than another.

This has a very important result in that any tendency which the belt mayotherwise have had to yield in such a way as to allow one edge to bepulled to a position in advance of the other and thus destroy theprecise 7 right angled position of the cartridge to the longitudinalaxis of the belt, is efi'ectuallyof paper having a plurality ofreinforcing eliminated.

While eyelet fastening means applied in the manner indicated in Fig. 1are the preferred form of construction, itis possible to utilize otherways of attaching the strips together and secure the "advantages to behad by grouping a plurality of cords along each margin ofthe'beltstrips. 7, in Fig. '3 of the drawing 1 have shown the use of-eyeletmembers 5 placed in such position with relation to the reinforcing cordsthat the flanges of the eyelets overlap the cords on either side andthus provide a very secure and effective construction. L

Still another form of fastening means that is well adapted to thepurpose is shown in Fig. 3 of the drawing in the form of clip members 8which are bent into place from opposite'edges of the strips and; aresufil ciently long to extend across bothadjacent threads in the mannerindicated. ln'l ig. 4 of the drawing the use of staples 9. is

' shown and it will be seen that in each form of the invention ordinaryandwell known forms of metallic paper fastening devices are made use ofto attach the belt "strips fto-' gether to provide a beltstructuresuiflciently well reinforced by the reinforcing cords towithstand any strain to which it is likely to be subjected; to ri idlyhold the cars tridges'in the proper position for feeding;

and, at the same time, provide a construction that is much lighter,takes up less space, and isa great deal less expensive than cartrigebelt constructions now known and used. V v
